2、vanced software tools with which most people are unfamiliar delay investigation initiation.Description of Driving Event: A criteria-based software tool selection process was not used for support of the Columbia Accident Investigation Board (CAIB). As a result, the primary Board and Task Force users

3、procured a software tool without fully understanding the capabilities and limitations of the software. In addition, investigation personnel were required to learn new software tools (e.g., databases), adding inefficiencies in Board and Task Force startup time.Lesson(s) Learned: A criteria-based tool

4、 selection process should have been implemented, and it should have been kept in mind that advanced software tools that most people are unfamiliar with, such as databases, cause delays in initiating an investigation. Further, the use of multiple software tools implemented to satisfy specific needs c
